In a study of crime, the fbi found that 13.2% of all americans had been victims of crime during a 1-year period. this result was based on a sample of 1,105. estimate the percentage of u. s. adults who were victims at the 90% confidence level. what is the lower bound of the confidence interval?

The lower bound of confidence interval would be 0.116.

Step-by-step explanation:

Since we have given that

p = 13.2%= 0.132

n = 1105

At 90%  confidence,

z = 1.645

So, Margin of error would be

So, the lower bound of the confidence interval would be

Hence, the lower bound of confidence interval would be 0.116.
